Hornady load data.

Book mark at least 2 reloading references on your computer. I have 2 physical manuals, laymen and hornady.

I lasts end up bringing out a page from either the bullet or powder manufacture to use as well but after I do tests and or find a pet load I write on that print out and put it in my main manual for that specific load for later.

Always try to have a few references on hand, or ways to obtain the info. The internet is a beautiful thing.

I was getting blown out primers and head case separations with 25.0 grains of H335 in .223 reloading. Please let us know how the 25grains work out for you?

Happy reloading...

Are you using range pick-up brass?

If you are using once fired brass, then you may be cutting or reaming the primer pocket crimp too deep.

If your once fired brass is MG-fired, the white ring on the case web area shows up after the first or second FL sizing.

If you get neck splits on the first FL sizing for your brass lot, that's MG-fired brass.

Not trying to derail OP thread...

It was once fired Police range nickel brass, Speers. I tried other powders with the same brass with no issues.

OP, have you tried the 25grains of H335 yet? If so how did it work out for you? I may have done received a very hot batch of H335!

I'll probably get a time out for this but i sick of reading stupidity like this


I just wonder why people think that if the manual doesn't have data on the specific to the part number bullet that they are trying to use the data is no good? Let me give you guys a tip, outside of a really drastic change in bullet shape and bearing surface (i.e. the difference between a FMJ to a round nose) You will not see any difference in pressure or load data directly attributed to bullet bearing surface. That said you guy need to think deeper on this subject that the smaller your bullet is in length and diameter the less those differences make to muzzle velocity.

So read that as you can use any load manual published 55 grain .224 FMJ load data for your caliber for any 55 grain .224 Bullet you have on hand. The differences in pressure will be unnoticeable at best. you will not get the same velocity but no one does anyway. your bullet drops will be different but if you're looking up ballistic data in a load manual and think you can use that real world well you got a long way to go.

This also should be read that reloading manual are not etched in stone. Manuals should be read as a lab report for certifying the load recipe in the test weapon listed. Nothing more. They are a reference and have little bearing on what you will attain out of your weapon with your components using their data.

Loading some .223 and have some .224 Hornady 55g FMJ and I’m going to use H335. Can someone give me some load data please?

This is pure idiocy So you just trust anybody on the internet to supply you with data from god knows where??

The Hodgdon site doesn't list the Hornady 55gr FMJ-BT.

From Hornady 9th edition

H335 20.8gr 2800 fps 21.6gr 2900 fps, 22.4gr 3000 fps, 23.2gr 3100 fps @2.200" oal

Here's another amateur. "Oh they don't list the bullet i want to use so i guess I need to find the one source that has the exact bullet i want to use ion my load before i can do anything"

Reloading manuals don't use every bullet (or powder) and they often get you in the ballpark. It's up to you to fine tune the load and make it work. Even if you are just making rounds for plinking, you may not get an exact load. I recently loaded up some 45-70 with some 350gn bullets that are not listed in any of the three manuals I have. I used H4895 so the Hodgdon site puts a 350gn round between 53-59c. I looked at 56gn for some plinkers and Quickload shows them over pressure while manuals show them Ok for similar 350gn projectiles. While it's nice to open the book and see your exact bullet with the powder you have, it often does not work out that easily...at least for me

Most intelegent post so far

Thanks guys.. all the data I have been reading leads to about a 25 g load.

I don’t really have the time to work up loads , I probably will give up on loading.223 as it’s a major PITA and really not worth it for AR plinking ammo

All my handgun loads I have worked up and have loads I now like.

Here you go don't stand next to this guy at the range. don't know what he's shooting and he don't care enough to put forth the effort. There again some people shouldn't own guns

This example is one of the few complaints I have with Hornady. They have used the same exact data for H335 and 55 grain bullets in several of their last editions. In this case and only in this example, Hornady's data is unrealistic. They did this many years ago test and keep using the same data in all their newer manuals. They did this old test using a 26" bolt action rifle and in fact their data is very weak and does not produce the velocity they report. Why they don't retest one of the most popular calibers with the most popular bullet weight with the most popular powder, I don't know. Lazy? Plus the most popular .223 rifle now is AR-15's and they don't even test 55 grain in the AR platform. Rant over.
In this example, I can only say that you can trust Hodgdon's data for 55 FMJ bullets. You may want to start 10% less than Hodgdon's maximum data and work up. No way 23 grains of H335 and 55 fmj's gets 3200 fps even in a bolt action 26" barrel. Start lower and work up in your rifle.

And yet again another Amateur. It has been just in recent times that reloading manual have printed data for gas guns. WTF do think we did for the last 40 years buy factory ammo. If you don't know that the data you have in your book will not work for a gas gun you too have a long way to go. The AR15/10, Mini 14/30, and any other gas gun was designed to run at a narrow window of port pressure. you exceed that port pressure and you run into problems. Bullet weight and velocity are just one aspect of port pressure, Powder burn rate is a bigger factor and you guys that think you can just dump any old .223 in an AR and think you're good are so far off base you're not even in the same state let alone ball park

For gods sake guy educate yourself
